7 TILLER SAFETY IMPORTANT SAFETY INFORMATION Honda tillers are designed to cultivate earth outdoors. Other uses can result in injury to the operator or damage to the tiller and other property. Most injuries or property damage can be prevented if you follow all the instructions in this manual and on the tiller. The most common hazards are discussed below, along with the best way to protect yourself and others. Operator Responsibility You must be alert and in good physical condition to operate the tiller. Do not operate the tiller if you are tired, ill, or under the influence of alcohol, medication, or any substance that might impair your vision, dexterity, or judgment. Know how to stop the tiller quickly in case of emergency. Understand the use of all tiller controls. Keep a firm hold on the handlebars. They may tend to lift during clutch engagement. Be sure the drag bar is in place and properly adjusted. Be sure that anyone who operates the tiller receives proper instruction. Do not let children operate the tiller. Keep children and pets away from the area of operation. Before starting the engine, check that the tiller is not damaged and is in good condition. Carbon Monoxide Hazard Your tiller s exhaust contains poisonous carbon monoxide gas, which you cannot see or smell. Breathing carbon monoxide can KILL YOU IN MINUTES. For your safety: Do not start or operate the engine in any closed or partially enclosed area, such as a garage. Never run the tiller in a closed or even partially closed area where people or pets may be present. Never operate the tiller near open doors, windows, or vents. Get fresh air and seek medical attention immediately if you suspect you have inhaled carbon monoxide. Early symptoms of carbon monoxide exposure include headache, fatigue, shortness of breath, nausea, and dizziness. Continued exposure to carbon monoxide can cause loss of muscular coordination, loss of consciousness, and then death. 5

8 TILLER SAFETY Fire and Burn Hazards The exhaust system gets hot enough to ignite some materials. 6 Keep the tiller at least 3 feet (1 meter) away from buildings and other equipment during operation. Keep flammable materials away from the tiller. The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before storing the tiller indoors. Refuel With Care Gasoline is extremely flammable, and gasoline vapor can explode. Never remove the gas cap or add gasoline with the engine running. Allow the engine to cool if it has been in operation. Refuel only outdoors in a well-ventilated area and on a level surface. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Never smoke near gasoline, and keep other flames and sparks away. Do not overfill the fuel tank. Make sure that any spilled fuel has been wiped up and cleaned before starting the engine. Always store gasoline in an approved container. Avoid Rotating Tines Rotating tines can cause serious cuts and even amputate body parts. Keep away from the tine area whenever the engine is running. If you need to work around the tines to clear object accumulation or for any other reason, always shut off the engine. After striking a foreign object, stop the engine, remove the spark plug cap, thoroughly inspect the machine for any damage, and repair the damage before restarting and operating the machine. Wear heavy-duty gloves when you need to clean the tine area or handle the tines. Clear Tilling Area Never attempt to make any adjustments while the engine is running. A tine can throw rocks and other objects with enough force to cause serious injury. Before tilling, carefully inspect the area and remove all stones, sticks, bones, nails, pieces of wire, and other foreign objects. If children get close to the operation area, stop the tiller and shut off the engine. Never operate the tines over gravel.

9 TILLER SAFETY Keep Shields in Place Guards and shields are designed to protect you from being hit by thrown objects and to keep you from touching hot engine parts and moving components. For your safety and the safety of others, keep all shields in place when the engine is running. Wear Protective Clothing Wearing protective clothing will reduce your risk of injury. Do not wear loose clothing, jewelry, short pants, sandals, or go barefoot. Wear gloves, eye protection, a long-sleeved shirt, and long pants made of heavy material. Keep clothing fastened. Wear sturdy work boots with good toe protection and nonslip soles. Turn the Engine Off When Not Operating the Tiller If you need to leave the tiller for any reason, even just to inspect the area ahead, always turn the engine off. Slope Operation When tilling on slopes, keep the fuel tank less than half full to minimize fuel spillage. Till across the slope (at equally spaced intervals) rather than up and down it. Be very careful when changing the direction of the tiller on a slope. Do not use the tiller on a slope of more than 10. For your safety and the safety of others, exercise extreme care when using the tiller on a slope. Tilling Conditions Operate the tiller only in daylight or good artificial light. Do not operate the tiller at night or under poor light conditions. Never operate the machine at high transport speeds on hard or slippery surfaces. 7

10 TILLER SAFETY Attachments and Modifications Do not make any modifications to your tiller. Modifying your tiller or installing non-honda attachments can make your tiller unsafe. If you need attachments for your tiller, use only Honda Genuine attachments (see page 59). These products have been designed for your tiller. Non-Honda attachments are usually designed for universal applications. Although aftermarket attachments may fit on your tiller, they may not meet factory specifications and could make your tiller unsafe. 8

16 CONTROLS Starter Grip Pulling the starter grip operates the recoil starter to crank the engine for starting. STARTER GRIP Throttle Lever The throttle lever controls engine speed. FAST Moving the throttle lever in the directions shown makes the engine run faster or slower. Tine speed is controlled by adjusting the throttle lever. At the maximum throttle position, the tines will rotate at the highest speed. Moving the throttle lever toward the idle position will decrease the tine speed. Handlebar Height Adjuster Handlebar height can be adjusted to match operator height. For adjustment, see page 21. For normal tilling, the most comfortable operator position is with the handlebars at waist height. 14 SLOW THROTTLE LEVER HANDLEBAR HEIGHT ADJUSTER

17 CONTROLS Clutch Lever The clutch lever engages and disengages the transmission that drives the tines. The tiller tines begin to rotate once the engine is started and the clutch lever is squeezed. The tines may momentarily rotate after clutch lever is released. Drag Bar The drag bar controls tilling depth and should always be used when tilling. It enables you to compensate for the hardness of the soil. Ideal drag bar height will depend on the type of soil being tilled and soil conditions at the time of tilling. In general, the drag bar should be adjusted so that the tiller is tilted slightly backward. Front Wheel The front wheel is used to help move the tiller from one place to another. Lift the tiller by the handlebars to roll the tiller on the front wheel. Pull out on the wheel assembly, move it to the raised position, and then release the wheel assembly before tilling. Always stop the engine before lowering or raising the wheel. CLUTCH LEVER RETAINER PIN FRONT WHEEL DRAG BAR ENGAGED DISENGAGED TILLING POSITION TRANSPORT POSITION 15

18 BEFORE OPERATION ARE YOU READY TO GET STARTED? Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Knowledge Read and understand this manual. Know what the controls do and how to operate them. Familiarize yourself with the tiller and its operation before you begin using it. Know how to quickly disengage the controls and shut off the engine in case of an emergency. IS YOUR TILLER READY TO GO? For your safety, to ensure compliance with environmental regulations, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the tiller to check its condition. Be sure to take care of any problem you find, or have your servicing dealer correct it, before you operate the tiller. Failure to properly maintain this tiller, or failing to correct a problem before operation, could result in a significant malfunction. Some malfunctions can cause serious injuries or death. Always perform a pre-operation inspection before each operation and correct any problems. 16

19 Do not place flammable objects close to the engine. BEFORE OPERATION Before beginning your pre-operation checks, be sure the tiller is on a level surface and the engine switch is in the OFF position. Check the Engine Before each use, look around and underneath the engine for signs of oil or gasoline leaks. Check the oil level (see page 30). Check the air filter (see page 36). A dirty air filter will restrict air flow to the carburetor, reducing engine and tiller performance. Check the fuel level (see page 28). Starting with a full tank will help to eliminate or reduce operating interruptions for refueling. Check the transmission oil (see page 33). Check the Tiller Tiller outside Make sure that there are no flammable materials (dust, straw, etc.) near the engine. Clutch lever function Check that the lever operates smoothly. Wiring and cables Check the insulation of each wire and cable for tears and cuts. Check if there is any wire or cable pinched by the neighboring parts. Bolts and nuts tightens Check for looseness in fastened parts. Securely tighten all loose parts. Tines Check for excessive wear, damage, or looseness. Engine operation Start the engine. Check for abnormal sounds. (See pages 19 through 20 for starting procedure.) Check that the engine stops securely by operating the engine switch. (See page 24 for stopping procedure.)

23 OPERATION OPERATING THE CONTROLS FOR TILLING If the tines dig in but the machine will not move forward, move the handlebars from side to side. When turning, push down on the handlebars to bring the tiller s weight to the rear; this will make turning easier. Handlebar Height Adjustment Stop the engine before adjusting the handlebar height. HANDLEBAR HEIGHT ADJUSTER To adjust the handlebar height, loosen the handlebar height adjuster, select the appropriate holes, and tighten it. Clutch When the clutch lever is squeezed, the clutch is engaged and power is transmitted to the transmission. When the lever is released, the clutch is disengaged and power is not transmitted. CLUTCH LEVER 21

24 OPERATION Tilling Depth Adjustment The drag bar is used to control the tilling depth, which can be adjusted by removing the pin and retainer and sliding the drag bar up and down as necessary. During operation, if the machine jerks forward while tilling, press down on the handlebars. This will cause the drag bar to dig more deeply into the soil. RETAINER PIN DRAG BAR Front Wheel After getting to the tilling site, move the front wheel to the raised position before tiling. Always stop the engine before lowering or raising the wheel. To raise or lower the wheel, pull out the wheel assembly, move the wheel, and then release the wheel assembly. TILLING POSITION TRANSPORT POSITION FRONT WHEEL 22

25 OPERATION HANDLING TIPS Adjust the handlebar height to a comfortable position (waist height for normal tilling). The drag bar should always be used when tilling. It enables you to compensate for the hardness of the soil. The ideal height of the drag bar will depend on the type of soil being tilled and soil conditions at the time of tilling. In general, however, the drag bar should be adjusted so that the tiller is tilted slightly backward. If the machine jerks forward while tilling, press down on the handlebars. This will cause the drag bar to dig more deeply into the soil. If tines dig in but the machine will not move forward, move the handlebars from side to side. Stop the tines before crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Stop the engine immediately if the tiller vibrates abnormally. Check the tiller for damage or loose parts, and repair or replace them before using the tiller again. Vibration is usually a sign of trouble. 23

26 OPERATION STOPPING THE ENGINE To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal conditions, use the following procedure. 1. Release the clutch lever to the DISENGAGED position. Even if you release the clutch, the tine may not stop immediately. 2. Move the throttle lever to the slowest position.

44 SERVICING YOUR TILLER SPARK ARRESTER SERVICE (optional part) Your engine is not factory-equipped with a spark arrester. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. A spark arrester is available from Honda servicing dealers. The spark arrester must be serviced every 100 hours to keep it functioning as designed. If the engine has been running, the muffler will be very hot. Allow the muffler to cool before servicing the spark arrester. 1. Remove the three 5 mm bolts from the muffler protector, and remove the muffler protector. MUFFLER PROTECTOR 5 mm BOLTS SPECIAL SCREW SPARK ARRESTER 2. Remove the special screw from the spark arrester, and remove the spark arrester from the muffler. 3. Use a brush to remove carbon deposits from the spark arrester screen. Be careful to avoid damaging the screen. The spark arrester must be free of breaks and holes. Replace the spark arrester if it is damaged. 4. Install the spark arrester and muffler protector in the reverse order of disassembly. 42

45 STORAGE STORAGE PREPARATION Proper storage preparation is essential for keeping your tiller trouble free and looking good. The following steps will help to keep rust and corrosion from impairing your tiller s function and appearance, and will make the engine easier to start when you use the tiller again. Cleaning 1. Wash the tiller, including the underside. Engine Wash the engine by hand, and be careful to prevent water from entering the air cleaner. Using a garden hose or pressure washing equipment can force water into the air cleaner. Water in the air cleaner will soak the filter element and can enter the carburetor or engine cylinder, causing damage. Water contacting a hot engine can cause damage. If the engine has been running, allow it to cool for at least half an hour before washing. Tiller If using a garden hose or pressure washing equipment to clean the tiller, be careful to avoid getting water on the belts. Spraying water on hot tine shaft bearings can cause them to be damaged from cooling too quickly. 43

46 STORAGE 2. After washing the tiller, wipe dry all accessible surfaces. 3. Start the engine outdoors, and let it run until it reaches normal operating temperature to evaporate any water remaining on the engine. 4. While the engine is running, operate the clutch lever to expel water from the pulleys, belts, and other moving items. 5. Stop the engine and allow it to cool. 6. After the tiller is clean and dry, touch up any damaged paint and coat other areas with a light film of oil. Lubricate the throttle cable core with a silicone spray lubricant. Fuel Depending on the region where you operate your equipment, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 30 days and may cause damage to the carburetor and/or fuel system. Please check with your servicing dealer for local storage recommendations. Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your tiller deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced. The length of time that gasoline can be left in your fuel tank and carburetor without causing functional problems will vary with such factors as gasoline blend, your storage temperatures, and whether the fuel tank is partially or completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Very warm storage temperatures accelerate fuel deterioration. Fuel deterioration problems may occur within a few months, or even less if the gasoline was not fresh when you filled the fuel tank. 44

47 STORAGE The Distributor's Limited Warranty (U.S.) / Distributor's Warranty (CA.) does not cover fuel system damage or engine performance problems resulting from neglected storage preparation. You can extend fuel storage life by adding a gasoline stabilizer that is formulated for that purpose, or you can avoid fuel deterioration problems by draining the fuel tank and carburetor. Adding a Gasoline Stabilizer to Extend Fuel Storage Life When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel deterioration during storage. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. 1. Add gasoline stabilizer following manufacturer s instructions. 2. After adding a gasoline stabilizer, run the engine outdoors for 10 minutes to be sure that treated gasoline has replaced the untreated gasoline in the carburetor. 3. Stop the engine, and turn the fuel valve to the OFF position. 45

48 STORAGE Draining the Fuel Tank and Carburetor 1. Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel. 2. Loosen the carburetor drain knob, and then move the fuel valve to the ON position. Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. Stop the engine and let it cool before handling fuel. Keep heat, sparks, and flame away. Handle fuel only outdoors. Keep away from your vehicle. Wipe up spills immediately. CARBURETOR DRAIN KNOB 3. After all the fuel has drained into the container, tighten the drain knob securely. 46

49 STORAGE Engine Oil Change the engine oil (see page 31). Engine Cylinder 1. Remove the spark plug (see page 38). 2. Pour a teaspoon (5 cc) of clean engine oil into the cylinder. 3. Gently pull the starter grip several times to distribute the oil in the cylinder. 4. Reinstall the spark plug and spark plug cap. 5. Pull the starter grip slowly until you feel resistance, and then return the starter grip gently. This will close the valves so moisture cannot enter the engine cylinder. 47

50 STORAGE STORAGE PRECAUTIONS Follow Honda's recommendations for safe storage of your tiller. If your tiller will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated. If possible, avoid storage areas with high humidity, because that promotes rust and corrosion. Unless all fuel has been drained from the fuel tank, leave the fuel valve in the OFF position to reduce the possibility of fuel leakage. Place the tiller on a level surface. Tilting can cause fuel or oil leakage. Allow the engine to cool before storing in any enclosure. With the engine and exhaust system cool, cover the tiller to keep out dust. A hot engine and exhaust system can ignite or melt some materials. Do not use a plastic sheet as a dust cover. A nonporous cover will trap moisture around the tiller, promoting rust and corrosion. REMOVAL FROM STORAGE Check your tiller as described in the BEFORE OPERATION chapter of this manual (see page 16). If the fuel was drained during storage preparation, fill the tank with fresh gasoline. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. Gasoline oxidizes and deteriorates over time, causing hard starting. If the cylinder was coated with oil during storage preparation, the engine may smoke briefly at start-up. This is normal. 48

51 TRANSPORTING Follow Honda's recommendations for safe loading, unloading, and transporting your tiller. BEFORE LOADING If the engine has been running, allow it to cool for at least 15 minutes before loading the tiller on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials. To prevent fuel spillage, drain fuel from the fuel tank (see page 46). Always turn the engine switch to the OFF position. Make sure to turn the fuel valve OFF. LOADING AND UNLOADING If a suitable loading ramp is not available, two people should lift the tiller on and off the transport vehicle while holding the tiller level. Position the tiller so it sits flat on the bed of the transport vehicle. Tie the tiller down with rope or straps. Keep the tie-down rope or straps away from the controls, adjustment levers, cables, and the carburetor. The handlebar can be folded either front or back so the tiller will take up less space (see page 21). Fold to the back side. Fold to the front side. 49

You will need these serial numbers when ordering parts, and when making technical or warranty inquiries (see page 60). Engine serial number: Frame serial number: Date purchased: 52

55 TECHNICAL INFORMATION Carburetor Modification for High Altitude Operation At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions. High altitude performance can be improved by a specific modifications to the carburetor. If you always operate your tiller at altitudes above 5,000 feet (1,500 meters) have your servicing dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life. Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made. When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may cause the engine to overheat and result in serious engine damage. For use at low altitudes, have your servicing dealer return the carburetor to original factory specification. 53

56 TECHNICAL INFORMATION Emission Control System Information Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic. Honda utilizes appropriate air/fuel ratios and other emissions control systems to reduce the emissions of carbon monoxide, oxides of nitrogen and hydrocarbons. Additionally, Honda fuel systems utilize components and control technologies to reduce evaporative emissions. The U.S. and California Clean Air Acts, and Canadian Environmental Protection Act U.S. EPA, California and Canadian regulations require all manufacturers to furnish written instruction describing the operation and maintenance of emission control systems. The following instructions and procedures must be followed in order to keep the Honda engine emissions within the emission standards. Tampering and Altering Tampering is a violation of federal and California law. Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those acts that constitute tampering are: Removal or alteration of any part of intake, fuel, or exhaust system. Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside its design parameters. 54
